Abstract

In a network of co-operating hosts (80, 82, 84, 86, 88), a method and system for automatic re-assignment of software components (110, 112) of a failed host to co-operating monitoring (82, 86) or back-up hosts. In a preferred embodiment, a Central Information Repository (CIR), such as an LDAP server, keeps track of software components (110, 112) running on the network hosts (80, 82, 84, 86, 88) and a Monitoring Partnership Program (MPP), in which some hosts (80, 82, 84, 86, 88) monitor the activity of other hosts (80, 82, 84, 86, 88), is provided. Upon failure of a monitored host (84), a monitoring host (82, 86) detects the failure, and informs the other monitoring hosts (82, 86) or the other back-up hosts, if any, of the failure of the monitored host (84). The monitoring hosts (82, 86), and/or the back-up hosts query the CIR for obtaining the identity of the software components (110, 112) running on the failed host (84) before the failure, and select which such components (110, 112) each will start. The monitoring hosts (82, 86) and/or the back-up hosts then take over and start the failed components (110, 112). Upon recovery, the monitored host (84) queries the CIR and obtains the list of its software components, informs the CIR and the monitoring or back-up hosts (82, 86) that it will take over, and starts its components (110, 112), while the monitoring and/or the back-up hosts (82, 86) shut down the components (110, 112) they temporarily run.
